+# mbed-js-st-fw-nfc02a1-example
+Example project for using Flash storage to store JS code and NFC tag reading and writing.
+
+## Description
+This example project explains the following:
+* Reading and writing NFC tag
+* Use Flash storage to store Javascript source code which can be executed when the board is turned on.
+* Downloading JavaScript program from url.
+
+## To build:
+
+```
+git clone https://github.com/STMicroelectronics-CentralLabs/mbed-js-st-examples
+cd mbed-js-st-examples/mbed-js-st-fw-nfc02a1-example
+npm install
+gulp --target=NUCLEO_F429ZI
+```
+See build/out/NUCLEO_F429ZI/mbedos5.bin.
+
+## Errors building:
+When you will try to build, you will receive errors building the project, it is because you have not defined a few parameters. Try the following tasks:
+### * Configuration error
+
+Open build/jerryscript/targets/mbedos5/mbed_app.json and modify the file as follows:
+
+```
+{
+    "config": {
+        "network-interface": {
+            "help": "options are ETHERNET,WIFI_ESP8266,WIFI_ODIN,MESH_LOWPAN_ND,MESH_THREAD",
+            "value": "ETHERNET"
+        },
+        "mesh_radio_type": {
+        	"help": "options are ATMEL, MCR20",
+        	"value": "ATMEL"
+        },
+        "esp8266-tx": {
+            "help": "Pin used as TX (connects to ESP8266 RX)",
+            "value": "D1"
+        },
+        "esp8266-rx": {
+            "help": "Pin used as RX (connects to ESP8266 TX)",
+            "value": "D0"
+        },
+        "esp8266-debug": {
+            "value": false
+        },
+        "wifi-ssid": {
+            "value": "\"SSID\""
+        },
+        "wifi-password": {
+            "value": "\"Password\""
+        }
+    },
+    "macros": ["MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES",
+               "JERRY_JS_PARSER 1", "JSMBED_USE_RAW_SERIAL", "JSMBED_OVERRIDE_JERRY_PORT_CONSOLE"],
+    "target_overrides": {
+        "*": {
+            "target.features_add": ["NANOSTACK", "LOWPAN_ROUTER"],
+            "mbed-mesh-api.6lowpan-nd-channel-page": 0,
+            "mbed-mesh-api.6lowpan-nd-channel": 12,
+            "mbed-trace.enable": 0,
+            "mbed-http.http-buffer-size": 2048,
+            "platform.stdio-baud-rate": 115200,
+            "platform.stdio-convert-newlines": true
+        },
+        "NUCLEO_F429ZI": {
+            "target.restrict_size": "0x80000"
+        }
+    }
+}
+
+```
+where target.restrict_size is the size reserved for binary, the rest of the space will be used for Flash storage.
+
+### * Pin generation error
+For some boards e.g. NUCLEO_F429ZI, pin generation is failing in Jerryscript. For the time being, you can skip some pin expressions in configuration to build for most boards by following these steps:
+
+Open build/jerryscript/targets/mbedos5/tools/generate_pins.py
+
+Find this line:
+```
+        pins[pin.name] = evaluator.eval(expr.strip())
+```
+Put this line in try statement:
+```
+        try:
+            pins[pin.name] = evaluator.eval(expr.strip())
+        except:
+            print("[Warning] Skipping pin name: " + expr.strip())
+```
+
+### * Easy-connect error
+If easy-connect fails, try updating mbed-os library.
+
+Open terminal (in Linux, Mac OS X) or command prompt (in Windows) and run the following commands:
+```
+cd build/jerryscript/targets/mbedos5/mbed-os
+mbed update ca661f9d28526ca8f874b05432493a489c9671ea
+```
+
+### * Error initializing X-NUCLEO-NFC02A1 expansion board
+if you see this error on serial terminal:
+```
+Failed to init XNucleoNFC02A1 expansion board!
+Error:0x1
+```
+
+You have to move the 'X_NUCLEO_NFC02A1' library from 'mbed-js-st-fw-nfc02a1-example/node_modules/mbed-js-st-x-nucleo-nfc02a1/NFC02A1/X_NUCLEO_NFC02A1' to 'mbed-js-st-fw-nfc02a1-example/build/jerryscript/targets/mbedos5/X_NUCLEO_NFC02A1'
+
+Remember to Move, not Copy.
+
+## Serial port Testing
+Open any serial port terminal application of your choice using settings of 115200-8N1 and try the following functions:
+```js
+// To load a js source code from HTTP url and save in Flash storage, type the following command and press Ctrl+R to run.
+load_http_program('http://mysite.com/source.js');
+
+// To erase the Flash storage, type the following command and press Ctrl+R to run.
+erase_flash();
+
+// To reboot device,, type the following command and press Ctrl+R to run.
+reboot();
+```
+## Writing to flash from terminal
+If you want to write a JS program to Flash storage offline. Open any serial port terminal application of your choice and write JS code as you like and then press Ctrl+F to flash the code. If you want to test the code only, press Ctrl+R.
